The ADT7482 1 is a three-channel digital thermometer and undertemperature/overtemperature alarm for PCs and thermal management systems. It can measure the temperature in two remote locations, such as in the remote thermal diode in a CPU or GPU, or using a discrete diode connected transistor. This device also measures its own ambient temperature. One feature of the ADT7482 is series resistance cancellation where up to 1.5 k (typical) of resistance in series with each of the temperature monitoring diodes can be automatically cancelled from the temperature result, allowing noise filtering. The temperature of the remote thermal diodes and ambient temperature can be measured accurate to 1C. The temperature measurement range, which defaults to 0C to 127C, can be switched to a wider measurement range of from -55C to +150C.
